The use of a piezoelectric tube for the photoacoustic gas-phase determination of NO2 as a model analyte is demonstrated. The tube is made from lead zirconate titanate with 30 mm length and 5.35 mm internal diameter. Its inner and outer surfaces are coated with electrodes. The tube serves as both, re...
